The House de Rosa is a Llaelese house whose home is in Eastern Llael. However, they do have estates near Merywyn including a farm and vineyard overlooking the Black River.
The House of de Rosa is linked with the Order of the Golden Crucible. Many in the family are alchemists and those that aren't still have close ties to the Order.
The family is also known for having an extraordinary number of members who are gifted. Though those who manifest the gift are almost exclusively female. Quite a few female members are arcanists with some following other paths such as warcasters or arcane mechanics.
The symbol for the family is a blue rose. It symbolizes the love and prosperity that can be attained only by those who work to attain it. The family is known to be driven and accomplish goals that many others felt were nearly impossible. They push for a stronger, less dependent Llael unlike quite a few of their contemporaries.
The family are strong followers of Morrow and in the recent years have attempted to fight against the Khador and Sul-Menite invaders. They are believed to be working with and supplying the resistance.
